Outdoor Waterproof H.V. 33KV 11kv Power Transformer

1. S11 Type 11KV 33KV Outdoor Waterproof H.V. Oil Type Power Transformer

S9-M 11kv oil immersed distribution transformers are widely used for power supply & distribution in
industrial and civil occasions, to step down grid voltage (11, 10.5, 10, 6.3, 6KV) to line
voltage 400, which can serve both indoors and outdoors at an ambient
temperature range -25℃ to 40℃. With reasonable structure design, the transformers
are qualified to withstand short-circuit and overload, and are free of maintenance and easy to repair.
The transformers have S9 and advanced S11 series, the S11 is more recommended for less loss of both load and no-load.
Product standard: IEC60076 & GB1094 and GB/T6451
